All Implemented Interfaces:

public class VkFenceGetFdInfoKHR extends org.lwjgl.system.Struct<VkFenceGetFdInfoKHR> implements org.lwjgl.system.NativeResource
Structure describing a POSIX FD fence export operation.
Description

The properties of the file descriptor returned depend on the value of handleType. See VkExternalFenceHandleTypeFlagBits for a description of the properties of the defined external fence handle types.

Valid Usage
  • handleType must have been included in VkExportFenceCreateInfo::handleTypes when fence’s current payload was created
  • If handleType refers to a handle type with copy payload transference semantics, fence must be signaled, or have an associated fence signal operation pending execution
  • fence must not currently have its payload replaced by an imported payload as described below in Importing Fence Payloads unless that imported payload’s handle type was included in VkExternalFenceProperties::exportFromImportedHandleTypes for handleType
  • handleType must be defined as a POSIX file descriptor handle

  • Constructor Details

    • VkFenceGetFdInfoKHR

      public VkFenceGetFdInfoKHR(ByteBuffer container)
      Creates a VkFenceGetFdInfoKHR instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.
